![]() Just installed parts tonight and monitor works great ! This monitor also has internal audio capability. Researching this online, found another who had same problem which was corrected by replacing just these parts, so ordered two of the caps ( even though other "channel" fine ), and 2SC5707's to replace the 2SC5706's ( another hint found on-line ). Checked further and found that both SM power transistors in that circuit had dead shorts between all 3 pins. Pulled PS board again and carefully inspected-saw one "channel" of HV invertor for CCFL backlights had a "bulging" & split. ![]() ![]() Took it apart and PS 12V output was "pulsing" around 2.5 volts at that 1 Hz pace, no visible sign of cap failure, but replaced anyway-still "no go". Got it home and it also cleaned up very well-power led blinked about a 1 Hz rate & figured bad electrolytics again. ![]() Well, a couple weeks ago at work, they were carrying old CRT's, computers, & laser printers to the back room for recyclers to pick up-as they passed by my bench with a non-working 19" Optiquest "Q9" LCD, I quickly claimed it, thinking it would be another "easy" fix. Posted awhile back about a 19" Sceptre LCD computer monitor I found in trash which cleaned up well & only needed new filter caps in PS-still working great.Īfter getting rid of "standby" CRT, thought I'd keep my eyes open for another LCD as a "spare".
